There is, with limitations. The relevant part of GDPR is Article 22, "Automated individual decision-making, including profiling" (Full text: https://gdpr-info.eu/art-22-gdpr/)
This is probably the most restricted of the rights granted under GDPR. You have the right to manual review of algorithmic decisions, only when those decisions result in "legal effects concerning him or her or similarly significantly affects him or her."
Whether it applies to Google depends on how you interpret "similarly significantly affects," and that's something likely to vary from country to country and well beyond my experience with GDPR. If this were the US, I would expect that to include housing and employment. There's a much stronger argument that this right applies to a Google account if it represents a significant fraction of your business income.
Part of the problem it seems is that even if these actions are unfair and unjustified it still makes financial sense for these companies to be trigger happy with automated account bans rather than implementing a more nuanced and intelligent approach which would likely require some human intervention or investment in more intelligence automated systems.
If we had some way to request human review or dispute automated actions it would become far more expensive to take unjustified automated actions as people would just complain and request a human reviews the case. Personally I think we've become far too comfortable with tech companies making it almost impossible to contact them. Requiring a human review process for automated actions and requiring companies have some way for customers to contact a human would create jobs and give us some legal right to adequate consumer service. It's weird to me that we have rights when it comes to how our data is used (at least in the EU), but no right to basic consumer service when our business is destroyed overnight because Google takes some automated action.
